This template contains the plot outline for the second three acts of The Beast with a Billion Backs, which is the same as the plot of "5ACV06" (5ACV06). The content of this page is included on both of those articles to avoid the need to change the same content in two locations.
The crew somehow manages to return to Earth where Bender is hospitalized. To cheer him up, the crew invites Calculon to perform for him. Bender is so inspired by this that he stalks Calculon on a regular basis until Calculon names him his official stalker. Also, Fry becomes increasingly depressed now that he is again alone, especially when many other people are not.
Farnsworth further examines the Anomaly and discovers that there is an electromagnetic field around it, thus preventing Bender from entering it. He calls Wernstrom to apologize and invite him over to collaborate with him on the Anomaly. Wernstrom shows that the enhanced laws of electromagnetism around the Anomaly prevent electrical devices from entering, but living things can pass through unharmed. The two team up to try and mount a second expedition, but President Nixon contacts the military instead.
Zapp Brannigan is commissioned to lead the attack, while Farnsworth and Wernstrom are arrested for protesting. Seeing Colleen (who is Chief of Police) again proves to be too much for Fry, who stows away on board the Nimbus to find a place to be alone forever. Amy gives Kif one more sweet goodbye before he heads off for the attack. Bender is jealous that humans must do all the interesting and enjoyable parts of missions, and laments when Calculon informs him that there is truly no such thing as the League of Robots, which had been known to deal justice to the mistreatment of robots everywhere.
Bender feels worthless now that he feels vulnerable to abuse from humans, and resolves to commit suicide. But while he waits in the suicide booth for his doom, he falls through a trapdoor and finds himself in a dark room with hooded robots—it is the fabled League of Robots, led by Calculon himself. He puts Bender through a series of tests which he passes easily (they all involve drinking some kind of alcohol), after which Bender becomes the newest member of the League.
Once the Nimbus is in range of the Anomaly, Fry sneaks out of the ship to enter it. Zapp prepares a missile to fire at the Anomaly, but it gets stuck in the hatch, so he forces Kif to un-jam it. While he does so, Zapp impatiently and repeatedly presses the "fire" button, which causes Kif become stuck to the missile, his feet caught in the hatch. The missile launches, stretching out Kif's legs. Just before the missile can make contact with with the Anomaly, Kif's legs are stretched as far as they can and it is pulled back at full force to the ship. The missile flies backward into the wall of the Nimbus' bridge, crushing Kif to death.
Kif's remains are buried on Amphibios 9. Amy is distraught about Kif's death and is unsure if she will ever love again, while Bender brags about being a member of the League of Robots without actually giving away its existence to anyone. Basically what the robots do in their free time is brag about how weak and feeble humans are, but when Billionaire Bot presents a monocle made of a human eye, Bender destroys it, strictly enforcing in his own right that the League of Robots involves a no-humans policy. Many robots begin to hold Bender in high regard, though Calculon senses deception may be afoot.
While imprisoned in the Fulcrum County Prism, Farnsworth and Wernstrom receive a mini-Smell-O-Scope from Leela disguised as a cake, and discover that the Anomaly truly does lead to another universe. With the help of Farnsworth's old gargoyle Pazuzu, the two break out of prison to warn President Nixon. At this time, Fry drifts through the other universe and makes a discovery of his own: a colossal tentacled creature.
The episode ends with "To be continued".
